To all whom it m concern:

Be it known we, Eowaan SIMMONS and Wanna S. Dar, citizens of the United States, residing at Oroville, in the of Butte and State of California, have mvented new and useful vements in Ant skiddin Devices, of w ich the following is a s i cation.

e general object of this inventi n 15 the provision of an anti-skidding device particularl adapted for use in connection with automo ile wheels, said device comprising, essentially, a yoke which is ada ted to be dotachably and securely fastene to the felly of a wheel, said yoke having connected thereto at one end thereof a plurality of chains which are adapted to embrace the tire and be detachably connected at their free ends to the other end of saidinke.

In carrying out the objects of t e invention generally stated above, it will be understood, of course, that the essential features thereof are susceptible to changes in details and structural arran ements, one preferred and practical embodiment being shown in the accompanyin drawing, where1n:-

Figure 1 is a agmentary side elevat on of a wheel, showing the device appl ed thereto and constructed in accordance w th the invention. 2 is a section on the line 22 of Fig. 1. i 3 is a detail perspective of the yoke use in OOHDGCtlOD WIt-h the invention. Fig. 4 is a similar view of a hook used for'connecting the chains to the yoke.

Referring more particularly to the accompanying drawing, in which like reference characters designate similar parts, the numeral 5 indicates the felly of a wheel and the numeral 6 the tire therefor.

The device which comprises this invention consists of a substantial U-shaped yoke 7 having an arcuate reinforcing late 8 secured to its inner surface medial y the ends thereof by means of rivets or other suitable fasteners 9. The yoke 7 and the plate 8 are rovided with alined centrally located openlugs 10 which are adapted to receive the threaded adjusting bolt 11, said bolt being provided at its outer end with a uared portion 10 ada to receive a suitab e tool for turning sa d bolt when securing the device to a wheel. The extreme inner end of the bolt-11 is provided with an annular groove 13 adapted to receive the central opening 14 formed in the arcuate fastening plate 15. When securing the device to the wheel, the bolt 11 is adjusted inwardly until the plate 15 comes into contact wit the fell 5 and the plate 15 is held in its adj position by means of a nut 16 which is threaded upon the bolt 11 and which is adapted to engage the exterior surface of the yoke 7 thereby preventing the rotation of the bolt where y the plate 15 will be at all times retained in secure engagement with the fell 5.

Formed integrally with one end of the yoke 7 is a transverse plate 17 which is adapted to engage and extend longitudinally of the tire when the yoke is in position. The plate 17 is provided with a plurality of transverse openings 18 which are adapted to receive the bent ends 19 of the substantially U-shaped books 20. Each of the books 20 is adapted to receive one end of a chain 21, the other end of said chain bein adapted to be connected to a book 22 whic is similar in construction to the book 20, each of said hooks being adapted to be connected to the plate 23 having a plurality of opznings 24 therein for the rece tion of the nt portions of said hook. T e plate 23 is also ada ted to extend transversely of the yoke 7 w on in position and said late is provided upon one of its longitudinal edges with an extension which is bent to form an eye 25. The eye 25 is adapted to be mounted between the spaced alining eyes 26 formed upon the enlarged end 27 of the yoke 7. A pintle 28 is adapted to be assed through the eyes 26 and 27 when in a inin position whereb the late 23 is connecte to the yoke an the c ains 21 are thus securely held in engagement with the tire. In order to prevent the displacement of the pintle 26, the same is provided at one end thereof with a head 29 and adjacent the other end with a transverse opening 30 l which is adapted to receive a cotter pin 31.

It will be understood, of course, that in use, a plurality of anti-skidding devices such as has been described may be fastened to the wheel thus effectually preventing the skidding of the latter.

From the fore oing description taken in connection with t e accompanying drawing, it will be men that the invention contemplates providing an anti-skidding device which is simple in construction thus reducing the cost of manufacture of the same to a minimum and which is durable and efi'ective in carryi out the purpose for which it is design What is claimed is:

An anti-skidding device for tires including a oke sha ed to partly embrace the wheel elly, sai yoke including an in a1 transverse projected plate formed wit a series of longitudinally alined openings, the opposite end of the yoke being formed to provide one member of a hinge connection,

a second plate formed with a complementary hinge member to engage the yoke hin e connection, said second plate formed wit a longitudinally arranged series of openings respectively alining transversely with the openings of the first mentioned plate, whereby to provide for the securing of chains encircling the exposed portions 0 the tire directly transverse thereof, and

means carried by the yoke and engaging the 20 felly to exert a. strain on the connecting chains when in place.

In testimony whereof we aflix our signatures in presence of two witnesses.
